Abstract

Using 119SnIV as a diamagnetic probe in the perovskite lattice of AFeO3 oxides (A[double bond, length half m-dash]Ca, Sr), the Fe[double bond, length half m-dash] disproportionation (2FeIV⇄ FeIII+ FeV) is discussed. An electronic phenomenon previously described for CaFeO3 is detected in SrFeO3 due to the local breakdown of the electronic delocalisation. Steric interactions seem to be the predominant factor for explaining the oxidation state of iron in the SnIV environment.
